This fossil palm leaf (Sabalites sp.) found in Alaska can be seen in the Smithsonian’s National Museum of Natural History. Sixty million years ago, dense, wet forests covered North America, and many plants, including palms, grew in places such as Alaska where temperatures are too frigid for them today. A new study published in Science gives scientists a picture of when the Earth was warm and when it was cool over the past 485 million years.
